Answer:
Use the cosine rule
Step-by-step explanation:
1. Apply formula of c^2 = a^2 + b^2 - 2abcosC
2. Substitute known values in: c^2 = 36 + 4900 - 840cos120
3. Apply algebra and use the calculator
4. Final answer is 73.18 (2 decimal places)
Answer:
y = 107°
Step-by-step explanation:
As you can see from the markings on the triangle, this is an isosceles triangle (two sides are congruent).
An isosceles triangle has the base angles congruent too.
So at this point,
34 = x - 5
Solve for x,
34 = x - 5
x = 34 + 5
x = 39
Now, the total angle measure of triangle is 180°.
There are two angles ready to solve for y.
34 + 39 + y = 180
73 + y = 180
y = 180 - 73
y = 107°
